如何同时运行Console和Form

Question

我想写入控制台并在表单上绘图，我尝试使用

  Console cnsl = null;
      PrintWriter out = null;
       // creates a console object
         cnsl = System.console();

         // if console is not null
         if (cnsl != null) {

            // creates new print writer
            out = cnsl.writer();

            // prints
            out.println("Here is The Optimus Prime!!");
         }

但它没有打开控制台窗口，只打开了窗体窗口！
